Introduction: Periodontitis is an infectious disease of the supporting structures of the teeth and is triggered by complex, anaerobic, gram-negative specific periodontal bacteria. Thrombocytopenia is a hematological disease associated with decrease in the platelet count in the peripheral blood. Material and methods: A case control study was carried out in the Department of Oral medicine and diagnosis at Surendra dental college & Hospital Shri ganganagar. The study was divided into two groups, Group 1 and Group 2 comprising of 15 cases with thrombocytopenia and 15 cases without thrombocytopenia respectively. Both groups were examined for periodontal condition as well as blood tests was done to determine the platelet count. Results: In the present study, mean platelet count was higher in Group II as compared to Group I but the difference between the two groups was found to be statistically significant. The severity of periodontitis was greater in Group 1 than that of Group 2 and majority of the patients in Group 1 revealed severe periodontitis. Conclusion: Plaque control and motivation are of prime importance in thrombocytopenic subjects so as to prevent gingival hemorrhage and periodontal disease.
